Candidate-source decisions
Density and gender segregation effects in the culture of the caridean ornamental red cherry shrimp Neocaridina davidi Bouvier, 1904 (Caridea: Atyidae)
A 90-day juvenile density comparison measures growth and survival, not multigeneration complete-system capacity.
The distribution of the invasive shrimp Neocaridina davidi in relation to environmental parameters in a stream at Kunitachi, Tokyo, Japan
Reports field density and habitat associations, which cannot define capacity in a maintained home aquarium.
Life-history traits and ecological characteristics of the ornamental shrimp Neocaridina denticulata, recently introduced into the freshwater systems of Israel
Observes three laboratory generations without a replicated density or resource treatment and therefore does not test capacity.
Search outcome
The evidence base now distinguishes short grow-out density, field density and unreplicated multigeneration observation. No complete-system carrying-capacity experiment was located.
